The complexity of plant-pathogen interactions makes their dissection a challenging task for metabolomics studies. Here we are reporting on an integrated metabolomics networking approach combining gas chromatography/mass spectrometry (GC/MS) with Fourier transform ion cyclotron resonance/mass
Potato (Solanum tuberosum) hairy root cultures, established by infecting potato tuber discs with Agrobacterium rhizogenes, were used as a model system for the production of antimicrobial sesquiterpenes and lipoxygenase (LOX) metabolites. Of the four sesquiterpene phytoalexins (rishitin, lubimin,
Ethylene/oxygen (E/O(2)) elevates sesquiterpenoid stress metabolite (SSM) levels in potato (Solanum tuberosum L.) tuber tissue which is reacting hypersensitively. To determine whether E/O(2) retards SSM turnover, a measured amount of rishitin was applied to tuber tissue which was then incubated in
Levels of katahdinone (solavetivone), lubimin, rishitin, and phytuberin, sesquiterpenoid stress metabolites of white potato (Solanum tuberosum), were monitored in tuber slices which were challenged with an extract of Phytophthora infestans and incubated under controlled atmospheres. A mixture of
